THE SEDIMENTARY EVOLUTION AND PETROCHEMICAL CHARACTERISTICS OF THREE TECTONIC LAYERS IN NORTH CHINA |
| |
| Abstract: | The tectonic layers in North China terrane can be divided into geosynclinal, platform and diwa (geodepression) tectonic layers, This paper deala with the differences of the sedimentary environments, the rock types, the sedimentation rates and the petrochemical models of these tectonic layers. It also points out the evolutional regularities or characteristics of the sedimentation rates and petrochemical compositions of the stratigraphic systems from middle Proterozoic to Cenozoic era. |
